I have a couple LCD displays right now, which I'm going to screw around with for a while, but I was mostly considering using the exotic colored displays (yellow on dark blue, light red on dark red, white on blue).
You already have some good ones, but for me, sinking another $60 into a serial LCD is a little steep, when I could pay just as much for two attractive 4x20s (I'm almost becoming comfortable with my soldering ability not to worry at all about just frying these things
).
